Description

Technical Field

[0001] This utility model relates to the field of oil removal testing technology for drying heaters, and in particular to an electrical testing device for oil removal and leak prevention. Background Technology

[0002] Because the thermal conductivity of oil is much lower than that of metal, residual oil on the surface of the heating element will form an "insulating layer," hindering heat transfer to the drying space or materials. This causes the heating element itself to overheat (heat cannot be dissipated), accelerating its aging and shortening its lifespan. The drying area temperature will rise slowly, requiring extended heating time to reach the target temperature, increasing energy consumption. Furthermore, accidents caused by "leakage, short circuits, and electric shocks" in drying heaters are numerous. Therefore, the core of product testing and oil removal for drying heaters is to ensure that the equipment's safety performance meets standards and that heating efficiency is stable and its lifespan is extended. Both factors jointly determine product quality and reliability.

[0003] For product testing and degreasing of drying heaters, in actual operation, each product is tested individually before degreasing. However, during the process, it was found that there were omissions in testing and degreasing. Furthermore, individual testing cannot meet production needs and increases labor costs. Therefore, an electrical testing, degreasing, and leak-proof testing device is needed to meet the usage requirements. Utility Model Content

[0018] Example:

[0019] like Figure 1-2 As shown, this embodiment provides an electrical testing device for oil removal and leak prevention, including an electrical base box 1, a testing fixture 2, and a power tester 3. The electrical base box 1 is equipped with a first intermediate relay 4, an AC contactor 5, a time relay 6, a counter 7, a first green indicator light 8, a red indicator light 9, and a switch 10. The testing fixture 2 is equipped with a second intermediate relay 11, a stainless steel spring 12, a fan 13, a capacitor contactor 14, and a second green indicator light 15. The switch 10 has a power indicator light 16, and the testing fixture 2 has a red buzzer alarm 17. An external start switch 18 is connected to the electrical base box 1, the testing fixture 2, and the power tester 3; pressing the switch 1... The process begins with startup. Time relay 6 engages with AC contactor 5, counter 7 illuminates, and the product begins power-on for oil removal. Once completed, time relay 6 reaches its set parameters, intermediate relays 4 and 11 open, cooling time relay 6 activates, and disconnects after the cooling time is reached. Test time relay 6 activates, intermediate relays 4 and 11 engage, green indicator light 8 illuminates, and the power meter begins testing whether the product's function is within the set range. After testing, the relays open, power is within the acceptable range, red buzzer alarm 17 sounds, and a good product is silent. The tooling simultaneously tests three products, reducing on-site testing time and improving production efficiency.

[0020] In this invention, switch 10 receives 220V voltage and inputs it to time relay 6, which then inputs it to intermediate relay 4 and AC contactor 5. The 220V voltage passes through time relay 6, intermediate relay 4, and AC contactor 5 in sequence, thus meeting the circuit connection requirements for testing oil removal.

[0021] In this invention, the counter 7 is electrically connected to the red indicator light 9, the first intermediate relay 4 and the second intermediate relay 11 are electrically connected to the time relay 6, the other end of the first intermediate relay 4 and the second intermediate relay 11 is electrically connected to the first green indicator light 8, and the second intermediate relay 11 is electrically connected to the counter 7. The electrical connection between the counter 7 and the red indicator light 9, as well as the electrical connection between the first intermediate relay 4 and the second intermediate relay 11, the time relay 6, and the first green indicator light 8, allows for adjustment of the test cooling time and automatic on / off connection.

[0022] In this invention, the stainless steel spring 12 is electrically connected to the test voltage 110V; the test fixture 2 can detect the placement of the product and determine whether the product is properly installed.

[0023] In this invention, the fan 13 is electrically connected to a 12V power supply. The 12V voltage meets the usage requirements of the fan 13 and avoids damage to the fan 13 due to excessive voltage.

[0024] Working Principle: During use, the drying heater is installed in the test fixture. Switch 10 is pressed to start the process. Time relay 6 engages with AC contactor 5, counter 7 lights up, and the product begins degreasing. After completion, time relay 6 reaches the set parameters, intermediate relays 4 and 11 open, the cooling time relay in time relay 6 starts, and disconnects after the cooling time is reached. The test time relay in time relay 6 starts, intermediate relays 4 and 11 engage, green indicator light 8 lights up, and the power meter begins testing whether the product's function is within the set range. After testing, the relays open, the power is within the set range, and the red buzzer alarm 17 sounds. Good products are silent. The fixture simultaneously tests three products, reducing on-site testing time and improving production efficiency. The fixture also contains stainless steel springs 12. If a product is not properly installed in the fixture or a test switch is missed, the red buzzer alarm 17 will continuously sound, effectively preventing missed tests.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
